Half Price Books, the nation's largest family-owned new and used bookstore chain, is inviting its customers and other friends of the environment to determine how monies set aside from its current "B(eco)me Bagless" philanthropic campaign will be earmarked.

Five environmental organizations have been selected from several dozen nominated by Half Price Books employees, including The Arbor Day Foundation, The Land Institute, The National Wildlife Federation, The Natural Resources Defense Council and The Trust for Public Land. Visitors to www.halfpricebooks.com can cast a vote for their favorite charity once each day through Sunday, Oct.31. The organization with the most votes will receive the $25,000 donation from Half Price Books, and the remaining four organizations will each receive a $1,000 donation.
